Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this theory
The bright revealed content of book understands other advantages and effect of the utility model easily.
As shown in Figures 1 to 4, the utility model relates to a kind of pressure sheath, including guiding sheath 1 and can be from guide sheath
The expander conduit 4 passed through in pipe 1, guiding sheath 1 mainly play a part of to establish channel, and expander conduit 4 mainly plays expansion and draws
The effect led.The non-intrusive end of guiding sheath 1 is fixed with guide sheath connector 3, and guide sheath connector 3 can be connected with operation handle
It connects, the convenient insertion depth etc. to guiding sheath 1 operates;The non-intrusive end of expander conduit 4 is fixed with expander and connects
First 6, expander connector 6 can also external operation handle or other operation equipment, facilitate and expander conduit 4 be pushed into patient's body
It is interior.In order to facilitate the insertion of guiding sheath 1 and expander conduit 4, preferably applied outside guiding sheath 1 and expander conduit 4
Functional coating is covered, functional coating can be hydrophilic coating, lubricant coating or bioactivity coatings.
Further, it in order to make doctor more intuitively understand insertion depth, in the present invention, guides sheath 1 and expands
Sheath scale mark 2 and expander scale mark 5 are labeled on the outer tube wall of prop conduit 4 respectively.Sheath scale mark 2 and expansion
Prop scale mark 5 can be the various forms of expression, such as digital scale, word marking, size-mark or be simply to set mark
Will point, as long as doctor is facilitated to observe insertion depth, insertion position.
Pressure in renal plevis directly affects the health of patient, and the pressure in surgical procedure in renal plevis is excessive in order to prevent or mistake
It is small that patient is caused to damage, therefore, in the present invention, pressure sensitive device is preferably provided in pressure sheath, it is directly right
The intracorporal fluid pressure of patient's chamber is monitored, and greatly improves safety.Pressure sensor 7 can be by any in the prior art
Known mode is fixed in groove 11, for example, being fixed in groove 11 by bond adhesion or physical structure, the physics
Structure is fixed to can be the modes such as engaging common in the art either part cladding, as long as not influencing pressure sensor 7
Monitoring to pressure.
Specifically, in the present invention, it guides and forms fluted 11 on the outer wall of the insertion end of sheath 1, groove
11 can be the various shapes such as rectangle, square, circle;It is equipped with pressure sensor 7 in groove 11, pressure sensor 7 and more
Root sensing line is connected, and the sensing line being arranged in guiding 1 tube wall of sheath by more spreads out of the signal of pressure sensor 7,
The front end of sensing line is connected with pressure sensor 7, and the rear end for sensing line is connected with pressure signal converter(It should be noted
It is that in the present invention, transmission line is front end close to one end of guiding 1 insertion end of sheath, close to the non-intrusive of guiding sheath 1
The one end at end is rear end), pressure signal converter can be electrically connected with the display equipment of peripheral hardware, when pressure sensor 7 receives pressure
After force signal, for pressure signal by transmission line to pressure signal converter, pressure signal converter converts pressure signal
To be transmitted to display equipment after various forms of signals such as picture signal, curve signal or digital signal, user can be by aobvious
Show that equipment is directly read.After guiding sheath 1 enters in ureter, pressure sensor 7 directly connects with intra-ureteral liquid
Touching, can accurately and in real time monitor the variation of pressure in cavity, doctor can be transmitted according to pressure sensor 7 numerical value come out and
When adjust therapeutic scheme.
Further, the groove that circular ring shape can also be opened up in guiding sheath 1, fixed setting and circle in toroidal cavity
The outer diameter of the intermediate ring that annular groove matches, intermediate ring is equal with the guiding outer diameter of sheath 1, and groove 11 is opened up on intermediate ring,
Pressure sensor 7 is set in groove 11, since guiding sheath 1 is hose, may be bent in catheterization procedure, so as to
The working condition of pressure sensor 7 can be impacted;The quality of intermediate ring relatively guiding sheath 1 is hard, can rise to pressure sensor 7
Protective effect prevents it from because guiding sheath 1 bends to have an impact it, guaranteeing the accurate of sensing data at work
Degree.
Further, in the present invention, pressure signal converter can in a wired or wireless manner with display equipment
The signal of pressure sensor 7, can be transmitted to external display equipment by wired or wireless mode by electrical connection.When to have
When the mode of line is connected, it is external that guiding sheath 1 can use electric transmission line 32 on non-intrusive end or guide sheath connector 3
Interface 31 for being connected with display equipment is set, and specifically, one end of electric transmission line 32 is fixing end, is fixed on guiding
In sheath 1 or guide sheath connector 3, and the end is connected with pressure signal converter;The other end of electric transmission line 32 is movable end,
End is fixedly installed interface 31, and interface 31 can be common USB interface or PS/2 interface etc., and external equipment can be various
The display of size.When guide sheath connector 3 is wirelessly connected with display, nothing is equipped in guide sheath connector 3
Line communication module, wireless communication module are connected with pressure signal converter, meanwhile, it is equipped in the display of peripheral hardware and channel radio
The corresponding wireless communication receiver module of module is believed, for receiving the signal of pressure sensor 7.
Further, in another embodiment, interface 31 can be arranged in pressure sheath in the form of other, such as
Shown in Fig. 2, it can will be used to be arranged with the interface 31 that display equipment is connected in guide sheath connector 3, in this embodiment,
Interface 31 is identical as above-described selection mode.Further, when guide sheath connector 3 and display wirelessly phase
It when connection, also needs that power module is arranged in guide sheath, be used for pressure sensor 7 and wireless communication module power supply.
In the present invention, in order to fully ensure that the measurement accuracy of pressure sensor 7, more sensings should be avoided as far as possible
There is the case where cross-contact in line, be otherwise likely to result in signal and interfere with each other between each other, influence the measurement of pressure sensor 7
As a result precision.Therefore, in the utility model, part of the sensing line in guiding 1 tube wall of sheath is mutually non-cross.
Further, more sensing lines are uniformly distributed in guiding 1 tube wall inner circumferential of sheath, so that sensing line is mutual
Distance is farthest, can avoid generating signal interference between each other as far as possible.
In the present invention, pressure sensor 7 may include semiconductor (such as silicon wafer) pressure sensor, piezoelectric pressure
Sensor, optical fiber or optical pressure sensor, Perrault special type (Fabry-Perot type) pressure sensor, ultrasonic wave migration
Device and/or ultrasonic wave pressure transducer, magnetic-type pressure sensor, solid state pressure sensor etc. or any other pressure appropriate
Sensor.
To sum up, pressure sheath involved in the utility model can accurately show insertion position, while can be accurate and real
When monitor the variation of pressure in cavity, safety coefficient is high.In addition, pressure sheath structure involved in the utility model is simple,
It is easy to use, it is worth carrying out wide popularization and application.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
